When we ran into Paris Hilton and Stavros Niarchos bolting out of the Little Door on Friday night, we fully expected them to catch them partying with Britney, but as things turned out, the pair had other ideas in mind! When they turned up back at Paris' house, she claimed to our guys that she was going to bed - then dragged Stavros inside! Gee, wonder what they got up to in there - especially considering how Paris' vow of celibacy is still in effect!
